Hello,
I'm attempting to install Hmailserver Admin Tools onto my laptop, however I'm getting the below attached error and not sure how to resolve.
I have HMailserver running in a Hyper-V environment, on a server-2008 R2 box, on my network. It is running rock solid. The version is 5.4.1-B1951
Do I need to open any specific ports on the laptop/server?
Thanks
